PENClL- SHARPENERa SPECIFICATION forming part of Letters Patent No.342,350, dated May 25, 1886.

Application filed September 4, 1885. Serial No. 176,140. (No model.)

To all whom, it may concern:

Be it known that we, CHARLES E. GOULD and FRANK H. Goon, of Leominster,in the county of Vorcester, State of Massachusetts, have invented acertain new and useful Improvement in Pencil'Sharpeners, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to make and use the same, reference beinghadto theaccompanying drawings,forming part of this specification, in whichFigure 1 is a side elevation of our improved penciIsharpener; Fig. 2, atop plan View of the same; Fig. 3, a vertical longitudinal section ofthe chuck; Fig. 4, a vertical transverse section of the same, and Fig.Sadiagram showing a portion of the chuck.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

Our invention relates to that class of pencilsharpeners which aredesigned to be operated by hand or power; and it consists in a novelconstruction and arrangement of the parts, as hereinafter more fully setforth and claimed, by which a more effective and otherwise desirabledevice of this character is produced than is now in ordinary use.

The nature and operation of the improve ment will be readily understoodby all conversant with such matters from the following explanation:

In the drawings, A represents the base and B the body of the frame forsupporting the working parts of our device. Projecting horizontally fromthe body B, near the top of the same, there is a bracket, 0, providedwith two vertically-arranged standards, D, and mounted horizontally insaid standards there is a shaft, E, carrying at one end the disk H, andat the other the beveled pinion J, both of which are firmly secured tosaid shaft. A bracket, K, also projects horizontally from the body B,diagonally opposite the bracket 0, and pivoted by the screw L, to swinglaterally on the outer end of said last-named bracket, there is a stock,M, provided with the handle at and two vertically arranged standards, N.A chuck, O, is journaled horizontally in the standards N, said chuckbeing hollow and provided with a cap, 1?, which is secured thereto byscrews Threehorizontally-arranged rods, '0, are journaled equidistantfrom each other within the body of the chuck, the ends of the rodsresting loosely in holes formed in the cap I and end T of said body. Anarrow elon-.

gated plat-e, w, is attached at one of its edges to the under side ofeach of the rods 11, and secured to the outer side of each of saidplates, at that edge of the same which is opposite the rod r, there is arod, f, corresponding in length nearly with the length of the plate. Anelastic rubber band or tube, a, is disposed around the rods 0 f, theband acting contractively to force the plates 10 inwardly against thepenciland clamp or hold it firmly in position while being sharpened. Theend T and cap 1? are each provided with a centrally-arranged hole, 0',for receiving the pencil S.

The ends of the plates 20, adjoining the end T of the chuck O, flare orare bent outwardly, as shown at d in Fig. 5, to enable the pencil to bereadily inserted in the chuck.

The outer face of the disk H is provided with a circular sheet ofsand-paper, F, corresponding approximately with the size of the disk,the sand-paper being held in position on the disk by means of theannular clamp or plate B and a thumbscrew, vi, the screw passing throughthe clamp and paper into the disk H or shaft E.

Alarge miter-gear, Q, provided with a crank, Z, is journaled on astub-shaft, z, disposed in the upper portion of the body B, said gear intermeshing with the miter pinion J on the shaft E and with acorresponding miter-pinion, Y, which is secured to the chuck 0, betweenthe standards N, by means of the screw it.

In the use of our improvement the pencil to be sharpened is passedthrough the hole 0- in the end T of the chuck O, and thence between theplates w, through the hole 0', in the cap P, the end of the pencil beingcaused to protrude, as shown in Figs. 1 and 2. After the pencil has beeninserted in the chuck, the gear Q is turned by means of the handle Z inthe direction indicated by its arrow, thereby causing the disk H andchuck O to be revolved in the directions indicated by their respectivearrows. The stock M is then swung laterally in a horizontal plane on itspivot L by means of the handle m, to bring the protruding end of thepencil against the sand-paper, thereby causing it to be sharpened orpointed in a m anner which will be readily obvious without a moreexplicit description.

Having thus explained our invention, what we claim is- 1. In apencil-sharpener, a disk provided with an abrading-surl'ace, a chuckpivoted to swing at right angles to the plane of said disk, and acranked miter-gear engaging gears on said parts, whereby they aresimultaneously rotated in opposite directions.

2. In a pencil-sharpener, a disk provided with an abradingsurface, achuck pivoted on the frame at a point beyond the edge of the disk andforward of the plane thereof and adapted to swing in a plane at rightangles to the plane of said disk, and a cranked mitergear engaging gearson said parts, whereby they are simultaneously rotated in oppositedirections.

3. In a pencil'sharpener, the combination of the disk H, sand-paper F,covering the surface thereof, a plate, It, disposed over the center ofsaid sheet of sand-paper, and a screw, 1', passing through said plateand clamping said paper F at the center of the disk H.

4. In a pencil-sharpener, the combination, with a cranked miter-gear Q,of a shaft, E, provided with an abrading-disk, H, a pinion, J, connectedto said shaft and meshing with the miter Q, a swinging stock, M, and aclutch, 0, working therein and provided with a pinion, Y, meshing withsaid miter-gear Q.

5. In a pencil-sharpener, a chuck for holding thepeneil provided withthe rods 1) f, plates 10, and elastic band a, substantially as and forthe purpose specified.

6. In a pencil-sharpener, the chuck O, having the cap I? and end T, andprovided with the rods 1) f, plates 20, and elastic band a, combined andarranged to operate substantially as set forth.

7. In a pencil-sharpener, the plates 20, having the flaring ends (Z, incombination with the rods 1), elastic band a, and body of the chuck O,substantially as set forth.

8. The improved pencil-sharpener herein described, the same consistingof the body B, having the brackets O K, the journaled gear Q, providedwith the crank Z, the chuck 0, provided with the pinion Y, the disk H,provided with the paper F, clamp R and screw i, the shaft E, providedwith the pinion J, and the pivoted stock M, provided with the handle m,combined and arranged to operate substantially as described.
